Fix an infinite recursion while still surprising the selector warning by simply declaring body dynamic.
Remove an unused variable.
* Remove an unused label outlet.
* Add save and preview toggle controls to the work controller.
* Stubbed in and wool up their save and togglePreview: methods.
Add the ability to toggle between preview and editor modes. Since SETextView doesn’t have an editing mode, it has to be swapped with a UITextView, whereas UITextView manages to handle both states itself. Comparing the two, I don’t really see a difference.
Remove the tab bar in favor of a unified experience via UITextView.
